type of baitcasting rod and reel

Question
I want to get into baitcasting more and I need advice on rod and reel selection.

someone told me to use a 6.2:1 gear ratio for quick retrieves like buzzbaits and crankbaits and a 3.8:1 for slow retrieves like plastic worms and jig n pig and stuff like that.  Is this true?

Also, i know to use a medium action rod for bass fishing like this, but what is a good length rod to get for the two setups. I'm a huge fan of St. Croix Avid rods and I was thinking two 6 footers would suffice.  Please correct me if I'm wrong.  Thank you in advance for your help.

Answer
Matthew,
 I personally would not go as low as a 3.8:1 for anything other than bluegill.  6:1 and up is great for crankbaits and buzzbaits.  Match this with a medium action crankin' rod at about 6 1/2 feet.  As far as soft plastics go - A 5:1 is a good all around way to go.  You can always slow your retrieve; however, with too low of a retrieve rate, you will not have the speed if you need it with lures such as speed worms.  Matching a rod really depends on the weight of the lure.  However, any medium action from 6-7 foot would work.  With light lures a meduim-light may be best.  With heavier jigs and large 10 - 12 inch worms, a medium-heavy may be best.  

I hope this helps.  If not please feel free to ask again.

Sincerely,
Chris "Evin" Carter
